dated February 7, 1898.

Application filed June 6, 1892. Serial No. 435,728. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN ROBERTS, a citizen of the United, States,residing at Indianapolis,in the county of Marion and State of Indiana,have invented new and useful linprovements in Oil-Burners, of which thefollowing is a specification.

My invention relates to an improved oil burner for stoves, furnaces andopen grates, and is particularly adapted for the consumption ofpetroleum oil and consists in novel means employed for consuming the oilin its liquid state immediately after it is discharged from the oil exitto the furnace of the burner and in such a manner as to avoid previousevaporation as in other attachments or devices employed for thatpurpose.

The object of my invention is to provide a means whereby the oil will befed directly to and distributed evenly over the surface of the burnerand the absorbing material placed thereon, while in combustion, also toprovide means whereby the unconsumed gases in the flame will bethoroughly blended with a sufficient quantity of atmosphericair toproduce perfect combustion.

In the accompanying drawings illustrating my invention, similar numbersof reference designate like parts ihroughout the several views.

Figure l. is a sectional elevation of the burner taken through the lineA, B, see Fig. 2. and which I use in round stoves, Fig. 2. is a halfplan of the same, Fig. 3. is a plan view of an oblong burner embodyingmy invention, and, Fig. e. is a transverse sectional elevation of thesame.

The burner consists essentially of an oil chamber 1. which may be eitheroblong square, round, or oval in form, and has the upwardly projectingflange 2. formed on the edge of the top surface thereof to form a pan oroil reccptacle wherein the oil to be consumed is discharged. In this oilreceiving pan I place an incombustible absorbing materal 3. as as bestusfiber, sand or other suitable absorbing material, and pack it with itstop surface level with ihe tip or nipples of the oil exit nozzles i.that is slightly lower than the top beveled edge of the flange 2. Theoil nozzles are formed integral on the top wall 05 the burner and havetheir induction openings or ends projecting downwardly into the oilchamber, slightly below the center thereof, thus, as the oil is fed intothe chamber through its oilfeed pipe 5. the lower end of the nozzles 4..will be immersed to an amount of depth proportional to the amount of thetension of the confined air in the upper portion of the oilchamber andabove the surface of the oil, produced by the pressure or rate of flowof the liquid fuel flowing into the chamber 1. through its feed pipe 5.thereby forming a non-conducting medium or jacket by which the heat fromthe flame of the burner is intercepted and the vaporization of the oilis consequently avoided.

Around each of the oil nozzles 4:. are grouped a series of air ducts 6.which extend through the bottom of the burner through the oil chamberthereof and projecting slightly above the level of the outer edge of theflange 2. for the purpose of preventing waste oil from dripping throughthem when it reaches the level of the top edge of said flange 2.

I prefer to fit the burner into astove or furnace with its outer edgesor periphery in conract with the walls thereof so that the atmospherepassing through the grate of the stove beneath the burner will have nocommunication with the flame from the burner except through the airducts, pipes or tubes,6.thereby providing an effective means (through anumber of minute jets of air) of thoroughly mixing the partially ignitedoil with the oxygen of the air to produce and support a more perfectcombustion.

It is clear that in consequence of the lower ends of the nozzles 4..being beneath the surface of the oil confined in the chamber of theburner the oil when fed or slightly forced therein will compress the airconfined in said chamber, the tension of which will force the oil upthrough said nozzles to the surface of the burner where it is consumed.It is also clear, that, the oil, owing to the regular and equaldistribution or the oil nozzles 4 over the surface of the burner will beequally distributed over the surface of the absorbing material, and aflame of uniform intensity will be thereby produced and continuouslymaintained.

Having thus fully described the nature of my invention what I claim asnovel and use ful and desire to cover by Letters Patent of the UnitedStates therefor is:

1.- In an oil burner the combination with the oil chamber thereof, of anejecting oil nozzle formed on said chamber with its top ejecting endabove the top surface of said chamher, and its induction end projectinginto the interior of said chamber slightly beneath the surface of theliquid contained therein, and an absorbing material on the top surfaceof the chamber and surrounding the tips of said nozzles, substantiallyas set forth.

2. In an oil burner, the combination with the oil chamber thereof, ofthe oil nozzles formed on the top wall of said chamber with their topejecting ends or tips projecting above the surface of said chamber andits eduction ends projecting into the interior of the oil chamberthereof, an upwardly proj ecting flange extending along or around theedge thereof, of an oil nozzle projecting clownwardly in said chamberand beneath the surface of the oil contained therein and having its tipbeneath the level of said flange, and an absorbing material surroundingsaid nozzles on the surface of said burner, substantially as and for thepurpose set forth.

4:. In an oil burner, the combination with the oil chamber thereof, andan upwardly projecting flange extending along or around the top edge ofsaid chamber, of an oil-nozzle projecting downwardly in said chamber andbeneath the surface of the oil contain-ed therein, and having its tip ortop ejecting end beneath the level of said flange, an absorbing materialsurrounding said nozzles on the surface of said burner, and suitable airducts or pipes extending from the under surface of, through the interiorand above the top surface of said chamber and absorbing material,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

BENJAMIN R0 BEETS.
